Fox 2.0 Perf Series 4-6″ Rear Lift IFP Shocks for 2014-2016 Ram 3500 4WD

Fox 2.0 Perf Series 4-6 inches Rear Lift IFP Shocks for 2014-2016 Ram 3500 4WD

Part Number: 985-24-257

Summary: FOX Performance Series 2.0 IFP smooth body shocks are engineered to transform the performance of your Ram 3500. By utilizing an Internal Floating Piston (IFP) mono-tube design, these shocks separate the shock oil from the high-pressure nitrogen chamber to eliminate oil aeration. This configuration provides a comfortable on-road ride and predictable off-road handling even in tough conditions, specifically for vehicles with 4-6 inches of rear lift.

Features

• Internal Floating Piston (IFP): Mono-tube design separates shock oil from the high-pressure, nitrogen-charged gas chamber to provide maximum performance from the factory-tuned precision valving.
• Aluminum Body: 2.0” Impact extruded and CNC machined 6061-T6 clear anodized aluminum provides increased cooling capacity to ensure rust-resistant durability over time.
• High-Flow Piston: Race-developed high-flow piston design provides application-specific valving to ensure a predictable ride quality capable of handling rough road conditions.
• Heat-Treated Shaft: 5/8 inches hard chrome plated heat-treated alloy steel provides increased strength to ensure long-term hardware integrity.
• Redundant Sealing Pack: Main seal, wiper seal, and scraper seal system provides multi-layer protection to ensure oil containment and debris exclusion.

Frequently Asked Questions

What is the benefit of the IFP design?
The Internal Floating Piston (IFP) separates the oil from the nitrogen gas, which prevents oil aeration and allows the valving to function with maximum precision and consistency.

Are these shocks resistant to rust?
Yes, the shock bodies are constructed from impact-extruded 6061-T6 aluminum and are clear-anodized for a durable, rust-resistant finish.

Will these fit a single-rear-wheel Ram 3500?
No, according to the manufacturer fitment notes, these specific shocks are designed to fit Dually-Pickup models only.
